The honest summary
An Asko refrigerator that has stopped holding temperature is far more likely to have an airflow or sensing problem than a sealed-system fault. Confirm with an independent thermometer, compare the two compartments, and consider the defrost cycle before anyone mentions refrigerant. A full manual defrost is the owner-level test that separates the two.
What owners describe
- Fresh food warm, freezer cold — Airflow: the cold is made and not delivered.
- Display reading correctly while the cabinet is warm — A sensor reporting wrongly, which is the instrumented-appliance failure.
- Both compartments warming with the compressor running — Capacity lost. A different and more urgent branch.
- Frost across the freezer rear wall — The blockage itself, and the defrost cycle behind it.
- NEAR MISS: a large warm load added recently — Recovery takes hours, and a loaded cabinet takes most of a day.
The ranking that matters
- Iced evaporator from a failed defrost cycle — First, and it produces the warm-forward pattern that dominates this class.
- Sensor reporting incorrectly — Second, and specific to appliances that decide what to do from measurements.
- Evaporator fan not running — Third, and the same symptom without the frost sheet.
- Condenser fouled or clearance blocked — Fourth, and it costs capacity in warm weather.
- Sealed system — Last, least common, and the only one no owner check resolves.
What to look at first
- Put an independent thermometer in each compartment — The display is what the machine believes; the thermometer is what is true.
- Compare the two readings against each other — Warm-forward means airflow, both warm means capacity.
- Listen at the freezer for the evaporator fan — It separates an iced coil from a dead fan in seconds.
- Defrost fully and see whether cooling returns — The definitive owner-level test on this class.
What an owner can safely do
- Move perishables to a cooler with ice — A refrigerator holds food safely at 40 degrees Fahrenheit or below and that clock runs first.
Tools: cooler, iceAbout 20 min
- Put a thermometer in each compartment and compare with the display — A display that disagrees with the thermometer is itself the finding.

- Vacuum the condenser and clear the clearance around the cabinet — It removes a variable before any harder diagnosis begins.

- Empty the cabinet and defrost with the doors open overnight — If cooling returns afterwards, the defrost system is the subject. Stop here rather than removing the evaporator cover.

Before you touch it
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off, and the defrost heater sits immediately behind the panel most people want to remove. Never chip ice off an evaporator: the tubing is directly behind it and puncturing it ends the appliance and releases refrigerant into the room. On a built-in installation, find the isolation point before you start rather than during, because it is rarely behind the appliance.
When to stop and book someone
Call when cooling returns after a defrost and then fails again, because that names the defrost system and the repair is behind the evaporator cover. Call when the display and an independent thermometer disagree, because that is a sensing fault and it needs the machine's own diagnostics read. Call promptly if both compartments are warm with the compressor running continuously, and deal with the food before the appointment.

Where this page stops
This page is the class-level answer for an Asko refrigerator that will not cool. It publishes no sensor resistances, defrost intervals, refrigerant data or part numbers, because those differ between builds under this badge and sealed-system data is not owner information. Where a family- or model-specific page exists it carries the layout and diagnostics for that unit. Refrigerant handling is regulated work everywhere and stays outside this page.
